The exact etiology of GP is not known. However, some studies have found an association between vitamin D and Bone Mineral Status (BMD) status with GP in their study. Objectives: To assess the serum level of vitamin D, and BMD and to determine their association with growing pain in children. Methods: This cross-sectional analytical study was conducted in the Department of Paediatrics, Bangabandhu Sheikh Mujib Medical University (BSMMU). Sixty children between the age of 6 - 12 years were included in the study from March 2020 to August 2021. Children who fulfilled the Evans criteria of GP were enrolled as cases and thirty age and sex matched healthy children were recruited as the control in the study. Informed written consent was obtained from patients and parents. Serum 25-hydroxy-vitamin-D levels and BMD were performed among cases and controls and subsequently compared to see their association in growing pain. A preformed semi-structured questionnaire was completed for each participant which included socio-demographic, clinical and laboratory characteristics. Appropriate statistical tests were applied for data analysis and performed by SPSS version 22. A p-value less than 0.05 was considered as significant at a 95% confidence interval. Results: In this study, 96.7% of growing pain patients had hypovitaminosis D and among them,<span style="font-family: "> the majority (86.7%) was vitamin D deficient. There was a significant association between vitamin D with GP compared to healthy control. BMD was significantly lower in the lumbar vertebra (L1 -<span style="font-family: "> L4) and femoral neck region (both right and left) among GP children compared to the control group. Conclusion: From this study, it may be concluded that the majority of children with GP had hypovitaminosis D and low BMD status compared to the control. Vitamin D deficiency and low BMD status were significantly associated with children with growing pain. Institutional Review Board (I.R.B.) Clearance Certificate (NO.
